umount a filesystem

[gkd]

I have mounted a NFS volume on a HPUX but when i try to unmount the same i
am getting the following error.
*******output of the command*********
#umount /bcp
umount: /cdrom: Block device required
**************************************

/bcp is the dir wer i am mounting the NFS volume which is on a Sun server.

This is a HPUX 11 system. There is nothing in the cdrom and it is not
mounted. I dont know why the CDROM comes in to picture when i try to unmount
a different filesystem .Below is /etc/mnttab entry..

Is there any clue...

You might try "umount -v ..." to see if it gives you any more info.

Also, what happens if you do "umount 10.32.22.140:/hpux" ?

I tried the following the problem is still the same.

# umount -v /bcp
umount: /cdrom: Block device required
# umount 10.32.22.140:/hpux
umount: /cdrom: Block device required

Is there anyother way..

You might try "umount -n 10.32.22.140"
or
"umount -f /bcp"
